Between about age six and 11, children can experience the world in a wonderfully free way. Liberated from the limitations and frustrations of early childhood but not yet in the thick of the demands and concerns of adolescence, kids, in what classic psychology calls the "latency period," are avidly discovering their world and their own potential. You can guide and support this discovery process by the way you design your child's room.
Grade-schoolers are a mixed bag. Like younger kids, they still need space to play on the floor and kick up their heels in safety. But like older kids, they have to contend with a lot of homework. A good-size desk, a comfortable chair, and a minimum of breakable knickknacks help satisfy both the big and little kid inside your grade-schooler.
